Working on Fonts in OOO Aqua port

I've been working on implementing text layouting in OpenOffice.org Aqua native port project.
Glyph, Character, Carets are beginning to work fine.

Fonts are the next part I'm working on currently.

But I need better screen refresh to be able to work faster.

I'll ask some help on Carbon mailing lists.

Playing with screen refresh...

Yesterday, being 4 hours on TGV, I continued to try to understand how to manage correctly screen refresh in my OOO Aqua build.... without success.

Information from Apple are a bit short about it and even with Quartz debugger, I did not succeed in having text refreshed correctly.

We use Quartz draw methods so we should use CGContextFlush but I must have missed something to use it correctly.
